AppellateGen: leaderboard

Appellate legal judgment generation in Chinese (AppellateGen, Yang et al., 2026): given a first-instance judgment and the facts newly found on appeal, a single model drafts the second-instance judgment for 1,000 test cases, half reversed and half affirmed. A DeepSeek-V3.2 judge scores verdict consistency (zero when the ruling direction is wrong), fact consistency, legal application and logical reasoning on 0-5 rubrics, and the score is their mean; higher is better.

Metric: Mean LLM-Judge Score (0-5; verdict, fact, legal application, reasoning). Source: arxiv.org. Saturation forecast: Around July 2028. 11 models tracked.
